Hi Nanthinee, Use ?rep it will rep()licate each x, freq times.
dat <- data.frame(freq = c(30, 70, 100, 22, 250), x = c(7, 8, 7, 6, 10)) total <- rep(dat$x, dat$freq) > length(total) [1] 472 Cheers, Josh On Thu, Jul 7, 2011 at 9:24 PM, nanthinee <nanthin...@gmail.com> wrote: > Hi, > > I have a dataset: > > freq x > 1 30 7 > 3 70 8 > 4 100 7 > 5 22 6 > 6 250 10 > > How do I convert into vector form (v<- 7,7,7,8,8,8,6,6,6,6) all "x" with the > complete frequency?
